The most noticeable aspect of the S100 is its split lower lumbar support, which flexes along with body movements.

    This Chair is Excellent

    My weight fluctuates between 255 and 280 pounds regularly. I have had this chair for a year and a half. I sit in it for four or five hours a day. It's still solid and comfortable. It's better than the more expensive ones that I bought, which claimed to hold 500 lbs. Definitely recommend this chair.

    Really comfortable and solidly built

    I put solidly built in the headline because I was looking for a chair for my Pop who is 6'4 and 300 lbs and he fits fine in it. Also it doesn't look like it would be that solid because it looks light and airy, I'm trying to say it's a good looking chair. Building it was about as easy as a chair with this many parts can be. To possibly save you some time I had a problem getting the back rest to stay up but if you pull up it will click, after each click you can stop and it will stay there, to lower it you pull all the way up and it will go down. For the price I don't feel like there is a better chair, I have plenty that cost more and this is right up there with them. As an aside, I needed to contact them with a question and they were super fast and friendly.

    Comfortable and sturdy, but takes time to assemble

    This chair is worth it once it's put together. It’s solid, comfortable, and offers good support for long hours at a desk. The adjustable headrest and tilt functions are nice touches, and everything feels well-made. The only downside is the assembly—there are a lot of pieces, and it takes some time to get through. It's not difficult, just more involved than expected. Still, once it’s set up, it feels like a quality chair that should last.

    Comfortable!

    Super comfortable and supportive! The dynamic lumbar and 4D armrests make long hours at the desk much easier. Easy to adjust and looks sleek in my home office.
